Abstract

LA INVENCION SE REFIERE A UN PROCESO PARA EL REACONDICIONAMIENTO DE ACIDOS CLAROS A PARTIR DE PRODUCCION DE DIOXIDO DE TITANIO SEGUN EL PROCEDIMIENTO DE SULFATO. MEDIANTE LA NEUTRALIZACION EN FORMA DE ETAPAS Y FILTRACION DEL OXIDO METALICO DEPOSITADO, EXTRACCION REACTIVA PARA LA ELIMINACION DE MAGNESIO Y MANGANESO, SE OBTIENE UNA SOLUCION DE SULFATO DE AMONIO ACUOSA, QUE EVENTUALMENTE SE SOMETE A UNA CRISTALIZACION DE EVAPORACION PARA LA FORMACION DE SULFATO DE AMONIO SOLIDO.
